Given
How to factor
Solution
Step 1
Multiply the first and last costant
Step 2
Write out all the pair factors of -6x^2
Step 3
Check for the pair, such that when you add you will get -x
Step 4
Replace -x with -3x+2x in the equation
Step 5
Put them into brackets Since + is at the center no stress.
Step 6
Factor out what is common in the bracket
Step 7
What is in the bracket are the same, pick one
Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
Use PEMDAS. Start by eliminating the exponents. you should be left with 3 numbers on bottom and 3 on top
multiply them then divide
Answer:
There are two equations and two variables, so this is a system of linear equations.
c + h = 360
4c = h
